3rd person doesn't suit any kind of pvp in arma IMO. No one can deny that 3rd person hurts pvp gameplay, since it's ridiculously exploitable.
I'm really sorry for those who don't have the patience to walk through the woods in 1st person, blame your adhd. I mean, have you actually tried walking in 1st person? Come on, it's not that bad...everything in ArmA needs patience.

I know mate, I just worry that my favourite playstyle will get hurt by all this. A server with vanilla/realism settings is already getting hard to come by.
I fear Bohemia will start catering to this new audience (most newcomers come to ArmA because of the sandbox aspect only) and eventually changing the game. I don't understand why people don't feel bothered with the fact that because of 3rd person, everyone can use a feature in a way that is clearly not intended for this kind of gameplay given the context of the game (milSim, realism). Giving you an ability that you shouldn't have when playing with other people turns into a broken mechanic. It's a simulator, you are supposed to have to walk to a corner if you want to take a look, instead of using the camera to check your surroundings without exposing yourself.
